To alt whom, tt may concern:

Be it'known that I, JOHN OSCAR N EIKrRK, a citizen of the United States, residing at Chi'- cago, in the county of Cook and State of Illiprovided with an operating-wheel mounted nois, have invented certain new andwuseful Improvements in Brake-O erating' Mechanisms for Cars, of which t e following is a specification.

t! My invention relates to that class of brakeoperating"mchanisms having a brake-shaft or staff operatively connected with the brake in any ordinary and well-known manner and thereon or connected therewith in such a manner as to be rotatable or have an orbital movement with relation to the shaft when out of operative position and adapted to operatively 'engageand rotate the shaft when 1n raised or operative position.

The principal obJect of my invention is to provide a simple, economical, and efficient rakefoperat' mechanism for cars.

A further object of the invention is to provide means for connecting the operatin wheel with the brakeshaft,`so as to permit the rotation or orbital movement of the wheel with'relation to the shaft when out of operative position and enable the Wheel .to be readily moved into and out of operative engagement with the shaft.

Other and further objects ofthe invention' will appear from an examination ofthe drawin and the following description and claims. he invention consists in the features,A combinations, and details of construction hereinafter described and claimed..

In the accompanying drawings, Figure 1 is aperspective view ofa brake-o erating mechanism constructed in accor ance with Am improvements, showing the brake-'wheel in raised operative osition or 1n position to rotate the brake-s aft; and Fig. 2, a view 'in elevation, showing the wheel in lowered osition-with its axis at an' angle to the axis o the shaft and in position to ermit'the independent rotation of the sha t or independent or bital movement of the wheel with relation to the shaft.

In constructing a brake-operating mechanism in accordance with my improvements I provide a brake-shaft a, which may be of the ordinary and well-known type and is opera-A tively connected with the rake mechanism of ,a car to be operated in any Ordinar known manner. .The end of the brake-sha is providedvwith a 'squared or angular tapered end .in fixed relation thereto and portionb. Upon thesquared end of the shaft is mounted a non-rotatable shouldered ber is mounted. The up'Ie'r portion of the non-rotatable sleeve mem ver c is square or angular on the outside as well -as the inner side thereof, and its lower portion is round or c lindrical so as to permit the vsupportings eeve o, thereon. This enables an ordinary'brakeshaft or staff with the ordinary squared and tapered end to be employed and provided with myimprovements. he side surfaces d ofthe ul'pper squared (portion ofv this non-rotatable eve c exten at an .angle with relation to each other', preferably at right an les, and are adapted to engage'the inner s ace ortions e of a supporting-bracketlf his supporting-bracket is secured ,to the-operating-wheel g'by means of a nut h, mounted ereinafter described, to rotate' u on and in threaded e agement. with its ii eaded end portion i. e upper neck portion of the bracket extends through the axial perforation ofthe wheel, beings uared, so as y to prevent the rotation of the w eel with re inte osed between the securing-nutan whee the nut being also further secured by means vof' a Cotter-pin k, which extends through a perforation 'l in the threaded end of the supportin bracket. The supportingbracket is providg m, the inner surfaces of which are adapted to lation to the bracket, and a washerg' mfy be the engage the sides orshoulder's of the operating sliou dered sleeve member'c when' the bracket and wheel are in raised operative position and may be moved out of engagement with'V such shoulder mechanism or'squared sleeve by being lowered to a position below the squared or.. shouldered portion thereof. VIn order to accomplish -tlus, the shaft is .provided with a supporting-sleeve n, mounted forming an annular vsup citing-shoulder or, 'supporting member, and` between this supporting-sleeve and the shouldered portion of the non-rotable sleeve memberc is rotatably mounteda supportin -sleeve o. encircles t e non-rotatable 'sleeve member c and may be in the form of a' split sleeve. It

is provided with preferablyintegral tunilioli Thisrstatable sleeve o` ed with parallel side portions portions p, adapted to be' snapped into p'e'rfo.A

rations or bearings g in the side ortions m of the bracket. The bracket is t us pivotally supported upon the rotatable sleeve, so as to swing in a vertical plane into and out of op-4 erative position and in a horizontal lane when in lowered or inoperative posltion. The side portions of the bracket are made of sufiicient length so that the brake-operating wheel may he thrown to the opposite side of the shaft from that upon which the pivot-pin p extends, so that when the brake-o eratmg wheel is lowered to the position s'own in Fig. 2 itis as near as possible to the shaft, thus occupying the minimum of space. When in lowered position, the bracket which supports the wheel is entirely below the shouldered portion of the sleeve member c, and the parts are thus in position to permit the rotation et the shaft, while the brake-op erating wheel and its supportingbracketA member are stationary. The brake-operat ing wheel and it.; supporting-bracket member may also when in this 'position' be moved orbitally with relation to the shaft, such movement beingpcrmitted by the rotatable sleeve, which supports the bracket and wheel thereon. This orbital movement of the`wheel while out of operative position enables it to be moved to any desired position which conditions may require, so as to occupy the minimum amount of space. The wheel may be raised into operative position and into operative engagement with the shaft by swinging it upward upon its horizontal pivots or trunnions when the ivotal center is at right angles with the si e portions of the shouldered member c, which are to engage the adjacent inner sides of the bracket member.

The bracket member may be inclosed on three sides. In other words, it may have a wall portion 1', (indicated by the dotted line in Fig. 2,) adapted to engage the shouldered mein ber when the wheel is in rafsed position, so that the axial center of the wheel will be supported substantially in alinement with the axial center of the shaft when in raised operative position and at the same time be capable of being readily swung to lowered position with its axial center at an angle to the axis of the shaft and in position to permit the independent movement of the wheel and shaft. Although a lever can be used under some circumstances in place of a wheel, l lind it gcnerally preferable to use a brake-operating wheel of the ordinary type.
